Abstract
A medical waste processing device includes an outer housing, material intake chamber having a passageway through which material passes, and cutting members contained within the housing that cuts and shreds the waste material before entering a waste receptacle that is located in the lower portion of the housing. A vacuum filter system is further provided to capture and filter potentially harmful aerosols that may be emitted during operation of the device. A method is also provided for reducing the volume of waste material through operation of the electrical shredding device.
Claims27
A waste processing device comprising:
- a housing having an upper region and a lower region;
- a material intake member and a cutting region located in the upper region;
- a pair of elongate counter-rotational cutting members located within the cutting region, said cutting members comprising a plurality of cutters having cutting teeth collectively forming a substantially helical pattern of cutting teeth along at least a portion of the longitudinal axis of said cutting members;
- wherein at least a portion of said cutting teeth comprise a forked end;
- spacers located between said cutters;
- a device to drive the pair of elongate cutting members;
- and
- a sensor for activating the opening and closing of said material intake member, said sensor includes a light emitting diode that emits infrared radiation.
